GRAIN-BIN.

and discharging them into different parts of the bin, until the bin isfull, and further to provide improved tilting chutes for the variousreceiving points ol the bin whereby gram from a Wagon bed maybeconducted into the portion of the bin designed to receive it.

My invention consists in the construction, arrangement and combinationof the various parts of the device, whereby the objects contemplated areattained, as hereinafter more -fully set forth, pointed out in my claimand illustrated in the accompanying drawings, in which Figure 1 shows avertical central sectional view of a grain bin embodying my invention.Fig. 2 shows an enlarged detail sectional view illustrating the latchdevice for releasing the tilting chutes, and Fig. 3 shows a horizontalsectional view taken on a line below the roof, an d showing thearrangement of the chutes in the bin.

Referring to the accompanying (.lrawings, I have used the referencenumeral 10 to indi cate the outer walls of the bin which issubstantially rectangular, and which support a roof 11. Parallel withtwo of the outer walls are two inner walls 12 extending from. one end tothe other, and arranged at right angles between these walls are theinner walls 13, thus forming two long compartments at the sides of thebin, and two short compartments at the ends thereof. The compartments atthe ends are each provided with a passage-way through which a loadedwagon may be driven to the space between the inner walls, one of saidpassage-ways being shown in Fig. 1.

At the top central portion of each inner wall I have provided a tiltinggrain chute comprising substantially triangular sides 14, and a bottom15. The chute is connected by hinges 16 with the inner wall, and thelower portions of the sides are shaped to rest against the adjacentportion of the inner wall, to limit the inward movement of the upper endof the chute, as shown to the left in Fig. 1. And when in said position,grain dumped into the top of the chute will be conveyed into thecompartment of the bin with which said chute is connected. When in saidposition, the upper end of the chute also projects out over the centralopening between the inner walls far enough to interfere with the passageof a wagon bed upwardly to a point above the chute, and therefore when awagon bed is being elevated, it will engage the chute and move it to theposition shown to the right in Fig. 1, then as soon as the wagon haspassed above it, it will drop by gravity to the position shown to theleft of Fig. 1, and be ready to receive grain discharged from the wagonbed.

I have provided for holding these chutes in their tilted positions asshown to the right in Fig. 1, as follows: One of the side pieces 14- ofthe chute is provided 'ith an opening 17, and the inner wall to whichthe chute is 5 hinged is provided with a spring actuated 1 slide bolt 18designed to enter the opening 17 when the chute is inits tiltedposition. Connected with the slide bolt is a rope 19 which passes over apulley 20 and extends do".vn wardly to a point where the operator maygrasp it and thus release the slide bolt from the chute, and permit thechute to drop by gravity to its normal position, as shown to the left inFig. 1. By this arrangement, any one of the chutes may be placed in itsnormal position by pulling upon the rope 19, or it may be placed in itstilted position by elevating the wagon bed. past it, and thus moving itto its tilted position, where it will be automatically held and lockedby the slide bolt.

Having thus describedv my invention, what .I claim and desire to secureby Letters Patent of the United States, is

An improved grain bin, comprising outer and inner walls formingcompartments between them, said inner walls forming a space between theminto which a wagon may be driven, and a tilting chute arranged at thetop of each inner wall, in one position being substantially in line withthe inner wall, and in another position being inclined inwardly to theposition designed to receive material and to conduct it into thecompartment below it, each chute being formed with an opening in one ofits sides, a slide bolt eonfrom the opening, the chute will drop bynected with the inner Wall adjacent to said gravity to its normalosition.
